IPC: G06T7/00
Filed: 1999-05-28
Abstract: A method of accurately locating a sub-pixel maximum on a two-dimensional grid (100) having an x axis and a y axis is provided. The method, which is suitable for locating a sub-pixel maximum, which falls at intermediate (200) grid points, begins identifying a grid point having a maximum grid point value (300). Then, a quadrangle containing a sub-pixel maximum is determined by locating neighboring grid points along the x and y axes (400), which have the greatest grid point values. Next, four one-dimensional, fractional maxima are computed along each side of a quadrangle. Next, two lines connecting one-dimensional maxima along the opposite sides of the quadrangle are computed. Finally, a location for the sub-pixel maximum is calculated where the two computed lines intersect (500).
